It's starting to look as if the trouble might have little or nothing to do with the armv6-armv7 transition and instead has some other cause. At this point /etc/make.conf contains KERNCONF=RPI2 TARGET=arm TARGET_ARCH=armv7 DESTDIR=/ Buildkernel works, installkernel demanded a DESTDIR and worked once it was added, so /etc/make.conf is being read and acted upon. If make buildworld is invoked, using the make.conf file above, make reports make[1]: "/usr/src/Makefile.inc1" line 450: To cross-build, set TARGET_ARCH. *** [buildworld] Error code 1 I had to reconstruct all of /usr after mistakenly deleting it during an attempted housecleaning. The restored /usr seems to boot normally and builds kernels just fine, but does not allow su to root, so permissions (or something) are not entirely correct. Might this be related to the failure to recognize or act upon the TARGET_ARCH=armv7 setting? /usr/src is at 324562, along with the kernel. Userland dates from late June. Thanks for reading, and any ideas. bob prohaska On Tue, Oct 10, 2017 at 08:00:21PM -0700, bob prohaska wrote: > On Tue, Oct 10, 2017 at 08:41:17PM -0600, Warner Losh wrote: > > On Tue, Oct 10, 2017 at 8:39 PM, Warner Losh <imp@bsdimp.com> wrote: > > > > > > > > > > > On Tue, Oct 10, 2017 at 8:33 PM, bob prohaska <fbsd@www.zefox.net> wrote: > > > > > >> On Mon, Oct 09, 2017 at 12:19:31PM -0600, Ian Lepore wrote: > > >> > On Mon, 2017-10-09 at 10:52 -0700, bob prohaska wrote: > > >> > > On an RPI2 model B, invoking? > > >> > > make -j4 -DNO_CLEAN MACHINE_ARCH=armv7 buildworld > buildworld.log > > >> > > > >> > Never set MACHINE_ARCH when building, use TARGET_ARCH. ?Be sure to set > > >> > TARGET_ARCH when installing as well. > > >> > > >> Tried it, like so: > > >> root@www:/usr/src # make -j4 buildworld TARGET_ARCH=armv7 > > > >> buildworld.log & [1] 1006 > > >> root@www:/usr/src # 1 error > > >> > > >> [1] Exit 2 make -j4 buildworld > > >> TARGET_ARCH=armv7 > buildworld.log > > >> root@www:/usr/src # more *.log > > >> --- buildworld --- > > >> make[1]: "/usr/src/Makefile.inc1" line 450: To cross-build, set > > >> TARGET_ARCH. > > >> *** [buildworld] Error code 1 > > >> > > >> make: stopped in /usr/src > > >> > > >> I also tried setting TARGET=arm and WITHOUT_SYSTEM_COMPILER=yes in various > > >> iterations.
